Ok, to solve that question:

[newbie] Trouble adding script to dynamically change CSS values based on conditions

That isn’t how you’d do it there. To do it there, you’d have to do something like <script type="text/discourse-plugin" version="0.4"> api.onPageChange((url, title) => { alert('test'); }); </script> My original post was from a plugin perspective.
